What would be better is a ranking system for this.  If a channel can be
recorded on more than one free capture card, it should pick the highest
ranked capture card rather than the first available.  Of course, if the
available capture cards all have the same ranking then it should act as
it currently does.  So for example, if there is a DVB card and an
analogue card.  I would rank the DVB card higher than the analog card,
as it does not require encoding and provides a better quality picture
and ,much better quality sound.

Deciding on one particular attribute such as stereo vs mono, IMHO is not
flexible.  IMHO, the ranking setting should by default be the same
number for all capture cards and in the mythsetup program's capture card
or inputsource section there should be an option to set the rankin of
the source.  Everyone is going to have different criteria for deciding
which source is best for them, so the ranking system would leave it very
flexible.  Its also a nice paradigm for users and one they can
understand.

If there is support for this idea, I will write a patch to implement
this.

Take Care
